"Prior to the invention of those instruments which can detect or generate radio waves, people didn't believe there was anything such as a radio wave. Why? Well, their physical senses could not detect it.

Because their physical senses do not (generally) detect the presense of spirits, souls, and such spiritual phenomena, they tend to not believe those exist either. Some people, however, do detect the presence of spirits, souls, ghosts, whatever.....but it's easy for someone who hasn't done so to just dismiss their reports and say, "Oh, they were having a hallucination." or "They're not telling the truth.""

LH I think you're pushing analogies a bit too far here: At one time people couldn't detect radio waves, just as, at the present time, people can't detect 'spirits', 'souls' and ghosts'. We now know that radio waves exist, therefore 'spirits', 'souls' and 'ghosts' must exist ... uuuummm ... give me a minute ... sorry, LH, but it sounds like very bad logic to me.

The fact is I'm not an unbeliever - I'm a sceptic - there is a big difference!
